"""常驻监听网站闭环端到端测试。
|
||
|
||
上一轮只验到注入假抓取的单测：真实抓取、真实 run_loop 轮次
|
||
边界、经服务端 API 的全链路（创建 -> 基线 -> 变化建任务 ->
|
||
暂停 -> 恢复 -> 失败退避 -> 结束）都没有跑过。本文件补这一环，
|
||
不改任何生产默认值、不改生产校验口径：
|
||
|
||
- 间隔仍是生产下限 60 秒；到期不是改间隔，而是给驱动传一个
|
||
更晚的 now（模拟时间流逝），与上一轮单测同款时间注入。
|
||
- 目标 URL 仍走生产校验：主机名 website-loop.test 不是 IP 字
|
||
面、不是 localhost，所以校验通过；测试进程内只把这个主机
|
||
名的 DNS 解析指向本地测试 HTTP 服务（相当于 /etc/hosts 的
|
||
一条测试条目），抓取本身走真实 default_fetch（urllib、超时、
|
||
1MB 截断），不注入假 fetcher、不绕过生产代码。
|
||
- 内容服务是线程内真实 http.server，可变内容、也可停服；
|
||
控制面是真实 ThreadingHTTPServer + 真实 SQLite 临时库；
|
||
变化建出的任务、轮询、审计都直接读库/接口核对。
|
||
|
||
不联网、不跑真实模型、不碰生产。
